There's a Futurama episode where Leela says: "This is, by a wide margin, the least likely thing that has ever happened."
Tonight I watched "The Family" where mobsters are searching for Robert DeNiro's family who are hiding out in Normandy, France - because the Witness Protection Program will go anywhere. How does the Mafia find where they are? The son writes a mundane quote in his school paper. This French school paper arrives in New York City via the only businessman in Normandy traveling to America. It arrives at the dump where a mafioso uses that very paper to wrap up some homemade hooch which just happens to be delivered to the very mob boss looking for the family. This sequence of events is so improbable you could write a mathematical formula for it.
